Fig. 3: Driving factors influencing the development of ARG and MRG.

A The changes of fecal copper concentration in feces. B The total abundance of MGE. C Pearson correlations between the total ARG abundance and total MRG abundance. D, E Pearson correlation between the fecal copper concentration and the total ARG (MRG) abundance. F, G Pearson correlation between the total MGE abundance and the total ARG (MRG) abundance. H, I Variation partitioning analysis for determining the contributions of different factors to the variations in ARG (MRG). CON control group, CS copper sulfate group, CP copper-peptide group, CR copper-rich period, CF copper-free period. Values are shown as mean and error bars represent SEM. n = 6 piglets/groups. Different letters represent significant differences; * represents significant differences; ns non-significant.
